Redislocation was seen in a few cases and was due to either rectus lengthening not being performed at initial surgery or failure to realign distally when a lateral patellar tendon insertion was detectable clinically, or reformation of contractures.

fislocation The diagnostic relevance of Q angle as an indication for distal realignment was not established in our case and we recommend tibial tuberosity-trochlear groove distance TTTG as measured by CT scan as a better tool. A year-old man consulted for limping. Treatment of chronic patellar dislocation with a modified Elmslie-Trillat procedure. Please review our privacy policy.

It is also termed as obligatory dislocation as the patella dislocates completely with each flexion and extension cycle of the knee and the patient has no control over the patella dislocating as he or she moves the knee. First-time patellar dislocation with resultant habitual dislocation two years later, which was not demonstrated on plain X-rays halfway: Patellar maltracking was persistent and so, it was decided to proceed with medial and distal transfer of tibial tuberosity.

We chose to assess treatment using functional scores. Various surgical techniques have been reported to treat pediatric population. Dislcoation pulling a suture through the holes disslocation femoral attachment point was found and with the help of a temporary pin in the medial epicondyle, favorable anisometry could be obtained the graft relaxed as the knee was flexed and a Corkscrew suture anchor Arthrex, Naples, FL, USA was put in place. Preoperative patellofemoral X-ray, tangential view in neutral rotation: Many surgical procedures using proximal realignment and distal realignment have been reported to treat HDP in children with satisfactory results.

Surgical Treatment of Habitual Patella Dislocation with Genu Valgum

A Two year after surgery, normal patella-femoral alignment was achieved. J Bone Dislcation Surg Br. Introduction Habitual dislocation of patella is a condition where the patella dislocates whenever the knee is flexed and spontaneously relocates with extension of the knee. If full flexion of knee is possible at this stage, vastus is repaired and the wound is closed.

In recurrent dislocations, there were no contractures of the soft tissue lateral to the patella, but medial stabilisation was found to be weak.

A number of reconstructive procedures have been described in the literature for the management of patellar instability. Presentation Lateral dislocation or subluxation of the patella in patellx can present in three different forms. They recommended that distal procedures alone are certain to fail, and if the procedure involves distal advancement of the tibial tendon the condition will actually be made worse.

In later childhood they present with habitual dislocation of the patella. There was a healed surgical scar over middle and lower third lateral aspect of the left thigh.

In other words it is essential to lengthen the quadriceps above the patella rather than to shorten it below the patella. Recurrent dislocation of the patella. The patient had a history of femoral growth plate fracture treated conservatively at 13 years of age.

We here report a case of habitual dislocation of the patella with genu valgum treated with a corrective osteotomy of the distal femur combined with lateral release and medial reefing.

Disorders of patellofemoral joint. Two-staged procedure was planned, first with patellar realignment and later with definitive total knee arthroplasty. A discussion on the etiology and relationship to recurrent dislocation of the patella.

Hagitual believe that the soft tissue surgery as primary procedure will buy additional time for patient to delay the TKA and proper patela tissue balancing will improve the longevity and clinical outcome of the definitive procedures.

Realignment procedures can be performed additionally to reduce the joint. The contractures were mainly seen in the vastus lateralis the main contributor in over half the cases and rarely in the iliotibial band or rectus femoris. However, lateral retinacular release alone was not sufficient to achieve joint reduction. Early results in patients with severe generalised ligamentous laxity and aplasis of the trochlear groove.

After confirming patellar centering during 4 to 6 flexion-extension cycles, the suture anchor was secured in its final position. On the postoperative radiograph, the congruence angle, sulcus angle, Q-angle, and Insall-salvati ratio was J Bone Joint Surg Am. Traditionally, habitual dislocation has been treated in the same way as recurrent dislocation except for the need for lengthening of the quadriceps tendon.
